摘要：

Electron rich chromium tricarbonylchloroarene complexes bearing an allyl ether moiety were cyclized under palladium catalysis with concomitant loss of the metal carbonyl fragment to give heterocyclic systems in moderate to good yields. Bimetallic catalysis with palladium and chromium compounds gave rise to cyclization of the parent chloroarenes in moderate yields and with low turnover numbers. (C) 1999 Elsevier Science Ltd.
